WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 233,763, dated October 26, 1880,

Application filed July 2, 1880. (No model.)

To all whom it may concern Be it known that we, J OHN M. HURD and JOHN lV. MOSHER, both of Auburn, in the county of Cayuga and State of New York, have invented a new and useful Improvement in Washing-Machines, of which the following is a specification.

Our invention relates to that class of washing machines in which the washing is performed by passing the clothes between a set of rollers held to their work by spring-power.

Heretofore in machines of this class the spring has generally been made of wood; but it is liable to become set and thus lose its power. A single spring of metal has also been used. Two flat steel springs of half-elliptical form have also been used with their convex faces resting one upon the other; but if they move and become abraded at the pointof contact particles of metal are liable to fall among the clothes and permanently stain them.

The object of our invention is to obviate these objectionable features 5 and it consists in the construction of a pressure-spring formed 2 5 of two plates bent in a half-elliptic form, provided with a hook at each end and a rivet in the center to retain the parts permanently immovable at that point.

It consists, also, in the means whereby the 0 machine is securely attached to the bottom of a tub and braced to the side thereof without materially injuring or disfiguring the latter.

In the accompanying drawings, making a part of this specification, Figure 1 represents 3 5 a perspective view of the washing-machine set in a tub, partly in section. Fig. 2 represents a horizontal section of the same, taken above the supporting-rollers. Fig. 3 is a perspective view of the double spring.

In said drawings, A and A are the side pieces of the frame of the machine; BB, the two lower rollers, over which and around the guide-roller (J is applied an endless canvas belt, D, in the usual manner.

E is the pressure-roller, mounted in sliding bearings a in the frames A A, so as to adjust itself to different thicknesses of the clothes to be operated upon, and which are passed and compressed between the rollers B and the roller E in the ordinary manner.

F represents the tub to which the washingmachine is attached.

G is the spring by the pressure of which upon the sliding bearings a a the roller E is held down against the rollers B. This spring is composed of two fiat metal springs, f and f, bent nearly half-elliptical in form, the central convex portion of one resting upon the convex portion of the other, at which point they are united by a rivet, g, to prevent one spring working upon the other at that point, whereby abrasion of the metal is avoided and the falling of metallic particles among the wet clothes is obviated. 4

In the machine the ends of the springs pass through vertical slots at in the side pieces, A and A, the lower spring-leaf, f, resting upon the sliding bearings a, while upon the upper leaf, f, a transverse bar,-I, is placed to receive straps H, pivoted at h to the side pieces, A and A. To keep the spring G from shifting endwise and escaping from the machine, the end of each leaf is made'in the form of a hook, it. The sides of the bearings a, being grooved vertically, are thereby retained securely con- 7 5 nected to the frame, and the lower leaf, f, of the spring being hooked thereto, the whole spring G is united to the frame, (as the two leaves are riveted together,) and the upper leaf, f, having hooked ends also, retains the bar I against displacement. The upper side of this bar is provided with a series of nails, 73, the heads of which project sufficiently to retain the straps H at any angle they may be set, the pressure of the spring G increasing with the inclination of said straps.

To retain the machine securely connected to the wash-tub F or other vessel, the side piece A of the frame is provided with a shoe, L, securely dovetailed to the lower end thereof. This shoe is of sufficient size to give a broad bearing for that end of the machine, and it is thus secured to the bottom of the tub by a couple of screws.

The side piece A rests upon the bottom of 5 the tub, and is braced to the rim F, or side thereof, with two hooks, M, pivoted to the piece A at m, the hooked end m of each engaging with screw eyes a, projecting from the inner side of the tub, adjoining the top thereof, to I00 give to the machine the required support to counteract the racking motion imparted thereto by the operator in rotating the crank N of the main roller E. By this mode of fastening, the machine can be promptly removed from the tub by the withdrawal of two screws, leaving no impediments within.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a washingmachine, the combination of two slotted pieces, A A, bearing-boxes (1, upper bar, I, a series of nails, 'i, thereon, and adjustable straps H, adapted to pass over the side pieces, A A, and nails 2' with a flat metal spring,f, having two hooked ends, K, turned JOHN M.
